编辑:我删除了id属性,然后遇到下一个错误,未定义的方法shopping\u list\u retailer\u id for Class:。为什么会这样
编辑:发现这是我从控制器调用的代码。。如果我回来
@购物清单零售商。购物清单产品
它很好用
但我会这样做:
api :GET, '/schedule/:schedule_id/requisition_plan/shopping_list/shopping_list_retailers/:shopping_list_retailer_id/shopping_list_products', 'List all shopping list products for Shopping List for Requisition Plans for Schedule in the database'
param :query, String, desc: "Scoped_search style query string"
def index
@shopping_list_products = ShoppingListProductsIndexQuery.new(@shopping_list_retailer, params[:query]).shopping_list_products
end
class ShoppingListProductsIndexQuery
attr_reader :shopping_list_retailer, :query
def initialize(shopping_list_retailer, query)
@shopping_list_retailer = shopping_list_retailer
@query = query
end
def shopping_list_products
@shopping_list_retailer.shopping_list_products.ordered_by_product_category_type_and_product_category_name_and_product_name.search_for(query)
end
end
仍然不明白为什么类的未定义方法id会在rabl视图中被命中。的错误消息未定义方法“id”表示未定义的方法位于类的实例上,而不是ShoppingListProduct的实例或任何实际的类名
这意味着渲染的对象是错误的
可能是因为您正在使用:
object :@shopping_list_products
# and
object :@shopping_list_product
而不是:
object @shopping_list_products
# and
object @shopping_list_product
移除:s
另外,在_show.json.rabl文件中,您确实不需要
object :shopping_list_product
因为当RABL模板用作部分模板时,会忽略这一点
